nodeTest
private org.apache.commons.jxpath.ri.compiler.NodeTest nodeTest
setStarted
private boolean setStarted
currentNodePointer
private org.apache.commons.jxpath.ri.model.NodePointer currentNodePointer
ParentContext

org.apache.commons.jxpath.ri.compiler.NodeTest nodeTest)
getCurrentNodePointer
public org.apache.commons.jxpath.ri.model.NodePointer getCurrentNodePointer()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Returns the current context node. Undefined before the beginning
of the iteration.
getCurrentPosition
public int getCurrentPosition()
getDocumentOrder
public int getDocumentOrder()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Determines the document order for this context.
reset
public void reset()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Sets current position = 0, which is the pre-iteration state.
setPosition
public boolean setPosition(int position)
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Moves the current position to the specified index. Used with integer
predicates to quickly get to the n'th element of the node set.
Returns false if the position is out of the node set range.
You can call it with 0 as the position argument to restart the iteration.
nextNode
public boolean nextNode()
- Description copied from class:
org.apache.commons.jxpath.ri.EvalContext
- Returns true if there is another object in the current set.
Switches the current position and node to the next object.
